The Rochester 3080-37 oil temp probe does come with the washer, nut and gasket.

Q: Does this probe operate on 12 and 24 volt systems?

Power is not connected to the Rochester oil temperature probe (3080-37) and therefore the voltage of your system is not a factor.

Q: Is this Rochester 3080-37 oil temp probe FAA/PMA approved and does it replace P/N S2335-1?

This unit does not come with FAA/PMA approval, but is the same make and model, and used for the same engine applications in experimental aircraft.

Q: Can this 3080-37 replace the S2334-4?

Per the manufacturer, there is no cross reference of this part to S2334-4, only to Cessna S32335-1.

Dynon recommends using Dynon probes with their EFIS systems.

Q: What is the 3080-37 probes length?

Approx 1/2 inch.

Q: Should the threaded end rotate?

Yes, the threaded end rotates on part # 3080-37.

Q: Does it work for a cessna 172 aircraft even does not coming with PMA/FAA?

Technically it should work but it would not come with the required documentation. Please consult with your A&P to determine if these could be legally installed in your aircraft.

Q: Will this sender work in a Piper PA28-180 with Lycoming engine?

Yes, this should be compatible with that engine.
